Looking for early marriage records

Could anyone tell me who or where to write for information about these two early marriage records? Perry Noggle married Nancy Wilson March 5, 1851, Berrien Co., MI Bathsheba Rachel Wilson married Benjamin (Lemon) Leemon March 18, 1855 Berrien Co., MI. I am also looking for any information on these two families.Family lore says that they stayed in the Berrien Co., MI area.
